What Is Iceberg Order?
An iceberg order is a large order that is divided into smaller, visible portions on the order book. Only a small fraction of the total order is displayed at any time — as each visible piece gets filled, a new portion is automatically placed. This hides the true size of the order from other market participants.
How Iceberg Order Works
Iceberg orders are used by institutional traders and whales who need to buy or sell large amounts without moving the market against themselves. If a whale placed a 1,000 BTC buy order visibly, other traders would front-run it, driving the price up before the whale could fill. By showing only 5-10 BTC at a time, the whale accumulates without revealing intent.
Why It Matters for Traders
Detecting iceberg orders is an edge in order flow analysis. Repeated fills at the same price level with consistent size, combined with bid depth that replenishes instantly after being hit, suggests iceberg activity. When you spot a persistent iceberg bid, it often indicates strong institutional support at that level — a potential long entry signal.
